LUMBAR ENDOSCOPIC PERCUTANEOUS DISCECTOMY - CLINICAL OUTCOME. PROSPECTIVE STUDY

ABSTRACT Objective: Lumbar disc herniation is a common indication for surgical treatment of the spine. Open microdiscectomy is the gold standard. New surgical techniques have emerged, such as spinal endoscopy. We compared and evaluated two endoscopic techniques: the transforaminal and the interlaminar. Methods: Fifty-five patients underwent endoscopic technique and were assessed by VAS and ODI in the preoperative period, and in the first and sixth month after the procedure. Results: We had 89.1% of good results and 10.9% of complications. Conclusion: We conclude that endoscopic techniques are safe and effective for the surgical treatment of lumbar disc herniation.

摘要
研究目的：腰椎间盘突出症是脊柱外科手术治疗的常见适应证。开放性显微椎间盘切除术（open microdiscectomy）是该病症的金标准治疗方案。近年来涌现出诸多新型脊柱外科手术技术，例如脊柱内镜技术（spinal endoscopy）。本研究对两种内镜手术方式——经椎间孔入路内镜术（transforaminal）与椎板间入路内镜术（interlaminar）——进行了对比与评估。
方法：本研究共纳入55例行内镜手术的患者，分别于术前、术后第1个月及第6个月，采用视觉模拟评分法（Visual Analogue Scale, VAS）与Oswestry功能障碍指数（Oswestry Disability Index, ODI）对患者进行疗效评估。
结果：本研究中患者的优良率为89.1%，并发症发生率为10.9%。
结论：本研究证实，内镜技术用于腰椎间盘突出症的外科治疗安全且有效。
